Wanting to Learn Sign Language

I want to learn sign language badly, I have the book signing for dummies, and I learned alot from it but I would love to take face to face classes, it's just so hard to find.

If anyone knows a school in Killeen, Tx that offers this class plz let me know and also I will be moving to Ft. Polk next yr. so if anyone know of any schools there that offers the class as well again plz let me know.
